REVISION SUMMARY
  Currently, [Ctrl] + [+] toggles the location bar between editable and breadcrumb modes, which is nice. However, it does this even when the URL bar is not focused, which can lead to times when you want to enter a path and instead accidentally make it un-editable, oops.
  
  This patch refines the behavior so that it only toggles the mode when the location bar has focus. This brings the behavior into 100% consistency with Dolphin, once D16980 <https://phabricator.kde.org/D16980> lands.

TEST PLAN
  - Compile and deploy
  - Open a file open/save dialog and make the location bar be breadcrumbs
  - Hit [Ctrl] + [L] twice in a row -> location field turns to being in breadcrumb mode. Focus is correctly returned to the main view.
  - Hit [Ctrl] + [L], move focus elsewhere, then hit [Ctrl] + [L] again -> Location bar is editable and focused.
